The transition from an ice age to an ice-free planet 300 million years ago was highly unstable, marked by dips and rises in carbon dioxide, extreme swings in climate and drastic effects on tropical vegetation, according to a study published in the journal Science Jan. 5. "This is the best documented record we have of what happens to the climate system during long-term global warming following an ice age," said Isabel Montanez, professor of geology at the University of California, Davis, and...

SALT LAKE CITY--(Oct. 13, 2005)--Prehistoric global warming episodes from massive atmospheric pollution involving carbon dioxide and methane could have created and preserved "mass kills" of wildlife, according to a University of Oregon study presented at the Geological Society of America's annual meeting. The work, done by Gregory Retallack, professor of geologic sciences at Oregon, involved a worldwide compilation of thousands of exceptionally well preserved fossil assemblages of fish,...

New Haven, Conn. - Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45 - 25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science Express. "Through the energy we consume, each of us makes a contribution to increasing greenhouse gasses, such as carbon dioxide and methane, in the Earth's atmosphere," said Pagani....

SANTA CRUZ, CA - Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago, according to a study published this week in the journal Science. James Zachos, professor of Earth sciences at the University of California, Santa Cruz, led an international team of...
